Photodissociation Dynamics: Spectroscopy and Fragmentation of Small Polyatomic Molecules

This article elucidates the achievements in calculating photodissociation move sections and fragment country distributions from first rules, ranging from multi-dimensional strength power surfaces and the Schrödinger equation of nuclear movement. Following a longer advent during which many of the forms of observables are defined, the following 4 chapters summarize the elemental theoretical instruments, particularly the time-independent and time-dependent quantum mechanical techniques in addition to the classical photograph of photodissociation.

Because only natural radioactive elements were available to him (artificial radioactivity was not yet discovered) which have high Z, the Coulomb corrections were large. 38 Fermi constructed his current-current interaction for nuclear β decay by mimicking the minimal couplings to currents in QED, and from this perspective it is natural that he did not include derivatives in his four-fermion theory. However, experiments at that time indicated that Fermi’s model predicted too few low energy electrons in β decay.

The name neutrino was later introduced by Fermi, to distinguish it from the real neutron which was discovered in the beginning of 1932 by Chadwick. [7]) With the discovery of the neutron and the proposal of a neutrino, the problems with the spin-statistics properties of nuclei disappeared,36 and one now needed a field theory for β decay. C. A. Becquerel got half of the third Nobel prize in 1903 “for his discovery of spontaneous radioactivity”. (The other half went to P. and Mme. Marie Curie “for their joint researches on the Radiation phenomena discovered by Professor Henri Becquerel”.

It was shown to be equivalent to earlier approaches [66], but because it was very complicated, equivalent to other approaches, and a mixture of quantum mechanics and field theory, it was soon abandoned by all physicists, including Dirac himself. 26 45 1. QED applied the Schr¨odinger equation to field theory. This had the drawback that manifest Lorentz invariance was lost when one switched from the relativistic action to the Hamiltonian operator. However, in the late 1940’s it was shown that if one uses the interaction picture, one may use minus the interaction Lagrangian Lint instead of plus the interaction Hamiltonian Hint to compute amplitudes [67].
